Some fixes for Ia2782d64 (2f60cd2)

- Add doTable() check at the top of renameIndex()
- Return true instead of false when aborting an update due to unfulfilled
  condition; false is only to be used for updates that will be written to
  a schema update file to be run later
  Also removed the return false from addIndex() for consistency
- Break long line
